After the boat crashes, call in an air strike on the specified location. Run up to the beach, and move to the right. You will find a small puddle at the right side of the beach. Stand in it briefly, then move towards the middle of the beach to find a smaller puddle. Stand in that puddle briefly. Move towards the far left side of the beach. Stand briefly in the puddle in the barb wire. After several seconds, the screen will shake, and you will hear strange voices. Four lion statues will rise out of the ground with alien Ray Guns in their mouths. -From: Chris Hauserman

3 enemies: Recon plane displays enemies on your team's radar.
5 enemies: Artillery strike that can be placed anywhere on the map.
7 enemies: Send out an angry pack of dogs against the enemy.

# Bonus Gamerpics

When you reach a new Prestige rank, you will unlock a Gamerpic matching the Prestige symbol. Reach the 10th Prestige to unlock the Sgt. Reznow Gamerpic.
# Easy Veteran mode

At the mission selection screen, choose a mission on the Veteran difficulty. After the first checkpoint, save the game, and quit. Go back to the mission selection screen, and choose the same mission, but change the difficulty to Recruit. While the mission is loading, you will see a white bar at the bottom of the screen. When the bar reaches approximately 33%, eject the disc or go to the Xbox Live Dashboard. Then, reload the game, and select "Resume". You should now be playing the mission on the Veteran difficulty, but with Recruit AI.
# Infinite ammunition

Use a gun with a bipod attachment. Lie down, deploy the bipod, and press Left Analog-stick Up. The ammo bar should disappear. You can now fire as long as desired without reloading or running out of ammo.

Take a machine gun that can be mounted, and mount it onto something or just the floor. Press Left Analog-stick Up, and your ammo bar will disappear. You will now have unlimited ammunition, but only while it is mounted.
# Extra ammunition

Use the following trick if run out or are running low on ammunition on any mission in Solo mode on any difficulty. Find a non-essential teammate (someone not involved in the story line). Walk up to him, and aim the reticule next to his head or torso. Knife the air, and as you do so move slightly towards them so that the reticule is over them. If done correctly, he should die and drop his weapon. Non-essential teammates will get replaced when you walk into a battle. If the teammate does not die but keeps getting back up, they are essential to the story (for example, Sgt. Roebuck and Sgt. Rezenov).
# Hide among the dead in Multiplayer mode

Find some dead bodies. Run up to them, and make sure no one else is around besides your teammates. Get down into a laying position. Then, crawl into what appears to be the body of the dead person, so it looks like there are fragments of the body around your HUD. Lower your gun, but have it high enough to still see what is coming. This trick will make it harder for people to see you unless they are paying close attention to the ground. The flaws to this trick are that people can sneak up from behind and see you, and you can only see in one direction without moving. After a few kills, move to another location because other players will pick up on your trick and grenade or rush you.
# Invincibility in Nacht Der Untoten

Play in Co-op mode. By the window at the back that you can see a truck out of, find a corner that is to the right of that window. Have one player go there, and crouch down. Have the other player jump on top of him. Then, have the player at the bottom stand up. You should now be inside each other and invincible as long as you do not move. If a zombie comes in, knife him. Shooting will not always work.
# Easy money in Nacht Der Untoten

For the first few rounds, let all the zombies break down the boards and come inside. Then, use your pistol or knife to kill them to get more points than simply shooting them once in the head. A knife to the head will earn 130 points per kill. Once all of the zombies are dead, patch up the boards. You will have much more money than if you simply killed them as they approached. Note: After level 3, the zombies are too powerful to be taken down this way.
# Preparing for next round in Nacht Der Untoten

At the end of each round, do not kill the last zombie. Kill all of the others, but allow one to live. When it has entered the building, throw a grenade at it to blow off its legs. It should now crawl slowly on the ground, leaving you plenty of time to patch up any necessary windows. The next round will not begin until you kill him. He is easy to evade. Use this opportunity to prepare for the next round. When you are ready, kill him to end the round.
# Hidden radio music in Nacht Der Untoten

Start any type of Nazi Zombie game, and unlock the door to the Mystery Box room. Go to the Mystery Box. Go over to the right, and look at a table to find a radio. Shoot a bullet at the radio. After a few seconds, you will hear random types of music such as rock, disco, opera, and some in-game music such as the Russian victory song, the final mission music, or the Japanese combat music. The music will stop in between rounds but will then start again. Every player in game should hear it.
# Sniping locations

Airfield

In the middle of the map is a two story concrete building. Place satchels or Bouncing Bettys to protect your location. There is also a large white estate with a ladder and staircase in front of it that can be used as a sniping location.

Castle

There are many good sniping positions on this map. The first is a small room overlooking the garden and the front staircase. To get to this room, either climb the ladder or go up the stairs. The second location is a small room that has a clear line of sight into the room mentioned above. To get to this room, go to the bottom of the map, and climb up the staircase. You should be on a wooden porch that connects to the gardens. Turn left, and you will be in the room.

Cliffside

There are two concrete bunkers in this map. Go to the one on the edge of the cliff. From this room, you can snipe players as they run by and also shoot them trying the get in from behind.

Courtyard

At the end of the courtyard, go into the shack, and turn right. Use the portion of wall that is jutting out to hop into the tree.

Dome

There is a platform with a ladder on the side of the building. To get to this platform, you can either climb the ladder or go up the stairs inside. This spot connects to a ledge inside the building.

Downfall

There is a bunker/cave in the upper left corner of the map (second row of buildings). This bunker has a clear shot of enemy respawn points and has good protection from tanks. Make sure to use Bouncing Bettys to protect yourself.

Hangar

On the second floor of the hangar is a small room. From the outside, you can get to it by climbing up the rubble pile on the side of the building.

Go to the porch outside the hanger entrance. Close to the hanger is a large white carved stone. Jump on it, and try and hop over the fence. You will fail, but will land on the fence.

Makin

Go to the circular building, and look through the stair entrance. There should be a hut with two rectangular windows overlooking the sandy area that can be used as a sniper position. Also, there is a tall building on the water with windows overlooking the entire map that can be used.

Outskirts

Once inside the church tower, look through the circular window. There is a white building with a small balcony in the distance. Use it to snipe from.

Roundhouse

There is a platform/hallway that goes over the middle of the map. To get to it, go behind the trashed locomotives. Climb up the staircase, and turn left at the round platform. You should have a good view of the whole roundhouse in the middle of the map.

Upheaval

Towards the top of the map is building with two windows that overlook the whole area. Note: Other players will try to get you.

Go into the house next to the burning house. Stand on a windowsill, and face the side. You should fall on a ledge below.

Enter the burning house. Go up the steps and out the window in the same way to hit a ledge below.

# Easy "Dead Air" achievement (Map Pack 2 DLC)

Open the door that has "Comm" on it in Shi No Numa. Then, open the door where the perk machine is located. There is a door on each side of the perk machine. Go in the one on the right. As soon as you enter that door, take a left. There is a black phone sitting on the table next to a radio. Go to the phone, and hold [Reload]. You may need to do this two or three times. You will start to hear numbers being dialed, it will start to ring, and you will get the "Dead Air" achievement.
# Easy "Gunslinger" achievement

After you get to the sniper spot to kill General Amsel, shoot all your pistol ammunition. Then, switch to your sniper rifle, then switch back to your pistol. You should now have 80 rounds of ammunition instead of only 13.

# Easy "Hammer Time" achievement (Map Pack 2 DLC)

Kill all but one zombie before they tear down the window boards. Let the last zombie live, and while he is tearing down the window boards, immediately repair them. Although you will not get points for repairing the boards, you will get the "Hammer Time" achievement. It is funny to watch the zombie get frustrated when it makes no progress, but do not get too close or it will reach through and take a swing at you.
# Easy "Rough Economy" achievement

Play through the "Vendetta" mission until you get to the part where you first assault the Nazis (directly after you are blown out of the building, then climb up a ladder with Sgt. Reznov to fight). This is the part where he talks about blowing up the flamethrower's fuel-packs to take out multiple enemies. Start killing enemies, making sure to take out the machine gunner in the far building, as he can throw off your aim. During the fight, four enemies will come out on a balcony to the left, at about the same height you are at. The closest enemy will be too far away from the others to get a group kill, and will actively target you; kill him. Wait until the remaining three enemies all stand and line up, then shoot through all three of them. They usually do not target you, as they are concentrated on the fight.

Play through the "Vendetta" mission. After you shoot General Amsel's guards and move up to the car with the sergeant, a group of Nazis will appear down the street. Do not follow the sergeant. Instead, stay near the car, and wait for three of the Nazis to get in a line, then shoot.
